I have a 1995 Sportage, 5 Speed Manual Tranny and I tow it 4-down all the time. I put the tranny in neutral and the transfer case in 2H. I just returned from a 5,000 mile trip towing the Sportage behind my motorhome with absolutely no problems. I do, however, try to stop about every 400 miles and start the engine and let it run a few minutes. By the way, towing instructions indicate 55mph maximum speed, but I believe that may have to do with manufacturer's liability or whatever. I routinely tow mine at 65-70mph with no problems.
